Definitions

  • Patent Application WO 00/26164 describes a process for the manufacture of DCE by chlorination of ethylene obtained by simplified cracking of ethane, the chlorination taking place in the presence of impurities obtained during the cracking of ethane without any other purification.
  • the washing agent that can be used for the absorption step A 1 therefore advantageously contains DCE in the liquid state.
  • the presence, in said washing agent, of other compounds is not at all excluded from the scope of the invention.
  • the washing agent contains at least 50 vol % of DCE, more particularly at least 80 vol % and most particularly preferably at least 95 vol %.
  • fraction F 1 contains at most 30%, preferably at most 20% and particularly preferably at most 15% of the compounds that are lighter than ethylene contained in the dry gas mixture.
  • the reactants may be introduced into the bed by any known device. It is generally advantageous to introduce the oxygen separately from the other reactants for safety reasons. These safety reasons also require keeping the gas mixture leaving the reactor or recycled thereto outside the limits of inflammability at the pressures and temperatures in question. It is preferable to maintain a so-called rich mixture, that is to say containing too little oxygen relative to the fuel to ignite. In this regard, the abundant presence (>2 vol %, preferably >5 vol %) of hydrogen would constitute a disadvantage given the wide inflammability range of this compound.
  • radical polymerization in aqueous suspension is understood to mean any radical polymerization process performed in aqueous medium in the presence of dispersants and oil-soluble radical initiators.
  • Fresh washing agent is added via the line 13 to the washing agent from column 9 and a purge 13 b is which conveys the washing agent towards an additional treatment (not shown) intended to reduce the concentration of the compounds that are heavier than ethane in the washing agent so that it is then reconveyed to the line 10 .
  • the stream of products 25 derived from the oxychlorination reactor is separated in 21 b is in DCE 24 accompanied by liquefied by-products among which water, by condensation followed by washing and gas/liquid separation.
  • the stream of products 31 derived from the oxychlorination reactor from which has been extracted the DCE 24 is then recycled to the reactor 3 .
